Mounting the Unit
Consider the following points before selecting where to install:
Do not mount the inverter on flammable construction
materials.
Mount on a solid surface
Install this inverter at eye level in order to allow the LCD
display to be read at all times.
For proper air circulation to dissipate heat, allow a clearance
of approx. 20 cm to the side and approx. 50 cm above and
below the unit.
The ambient temperature should be between 0°C and 55°C
to ensure optimal operation.
The recommended installation position is to be adhered to
the wall vertically.
Be sure to keep other objects and surfaces as shown in the
diagram to guarantee sufficient heat dissipation and to
have enough space for removing wires.

Install the unit by screwing three screws.
Battery Connection
CAUTION: For safety operation and regulation compliance, it's requested to install a separate DC over-current
protector or disconnect device between battery and inverter. It may not be requested to have a disconnect
device in some applications, however, it's still requested to have over-current protection installed. Please refer
to typical amperage in below table as required fuse or breaker size.

Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. 1KVA model supports 12VDC system, 2KVA/3KVA model supports 24VDC system and 4KVA/5KVA model
supports 48VDC system. Connect all battery packs as below chart. It's suggested to connect at least 100Ah
5
capacity battery for 1-3KVA model and at least 200Ah capacity battery for 4KVA/5KVA model.
NOTE: Please only use sealed lead acid battery or sealed GEL/AGM lead-acid battery.
3. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are
tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly
connected and ring terminals are tightly screwed to the battery terminals.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are
connected tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure
positive (+) must be connected to positive (+) and negative (-) must be connected to negative
(-).
6
AC Input/Output Connection
CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between
inverter and AC input power source. This will ensure the inverter can be securely disconnected during
maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 10A
for 1KVA, 20A for 2KVA, 32A for 3KVA , 40A for 4KVA and 50A for 5KVA.
CAUTION!! There are two terminal blocks with "IN" and "OUT" markings. Please do NOT mis-connect input
and output connectors.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC input
connection. To reduce risk of injury, please use the proper recommended cable size as below.
Suggested cable requirement for AC wires
Model Gauge Torque Value
1KVA 16 AWG 0.5~ 0.6 Nm
2KVA 14 AWG 0.8~ 1.0 Nm
3KVA 12 AWG 1.2~ 1.6 Nm
4KVA 10 AWG 1.4~1.6Nm
5KVA 8 AWG 1.4~1.6Nm
Please follow below steps to implement AC input/output connection:
1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be
sure to connect PE protective conductor ( ) first.

WARNING:
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
4. Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws.
Be sure to connect PE protective conductor ( ) first.

5. Make sure the wires are securely connected.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause
utility short-circuited when these inverters are worked in parallel operation.
CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it's required
to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a
short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check
manufacturer of air conditioner if it's equipped with time-delay function before installation. Otherwise, this
inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes
internal damage to the air conditioner.
PV Connection (Only apply for the model with solar charger)
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important for system safety and efficient operation to use appropriate cable for PV
module connection. To reduce risk of injury, please use the proper recommended cable size as below.
